- wxWindow::OnInternalIdle is now used in all ports, and ensures that user OnIdle events do not interfere with crucial internal processing. - wxWindow::UpdateWindowUI is now a documented function that sends wxUpdateUIEvents, and can be overridden. It has a helper function DoUpdateWindowUI for taking appropriate wxUpdateUIEvent action. - Added functions to wxUpdateUIEvent: Set/GetMode, Set/GetUpdateInterval, CanUpdate, to assist with optimising update event frequency. - Added functions to wxIdleEvent: Set/GetMode, CanSend, to determine whether a window should receive idle events. - Added wxWS_EX_PROCESS_IDLE, wxWS_EX_PROCESS_UI_UPDATES window styles for use with conservative idle and update event modes. - wxMSW and wxGTK now send menu update events only when a menu is about to be used. - Added WM_INITMENU processing instead of WM_ENTERMENULOOP, or accelerators don't always get called since menu items may still be disabled. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@21789 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
